The modular system once developed by Robert "Bob" Moog went through a long production period between 1964 and 1981, including its development process. At that time, the new, electronic instrument was an avant-garde pioneering work that still had to be explained to the public, but ultimately found more and more interested parties. Behringer has transferred the generously dimensioned dimensions to the compact Eurorack format and paid close attention to ensuring that the sound and function are in no way inferior to the cult object.

The CP3A-M from Behringer is an audio mixer with four level-adjustable inputs. The outputs are dual and available with positive and negative amplitude; this allows a waveform to be reversed. The CP3A-M is functionally enhanced by two 1 to 3 multiples.
